import java.util.Properties;



import javax.mail.Address;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;



public class demo01 {

	public static void main(String[] args) throws Exception {

		Properties props = new Properties();

		props.setProperty("mail.smtp.auth", "true");

		props.setProperty("mail.transport.protocol", "smtp");

		Session session = Session.getInstance(props);

		session.setDebug(true);

		Message msg = new MimeMessage(session);

		



		msg.setFrom(new InternetAddress("test@163.com"));

		msg.setText("这是邮件内容");

		

		Transport transport = session.getTransport();



		transport.connect("smtp.163.com", 25, "test", "123456");

		transport.send(msg,new Address[]{new InternetAddress("xingguang_2010@163.com")});

		transport.close();



	}



}

运行后报了以下错什么原因(不管运行多少次，都报一样的错)
